LED Lighting Wi-Fi Network

Researchers at the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute HHI in Berlin, have been working on using a LED lighting system to double as a 800 Mbps wireless network, apparently each light would have a cool ninety square foot range making it ideal for public buildings and large offices. The first time something like this was seen was in 2008, it was when the US Science Foundation gave an $18.5m grant to researchers at the University of Boston, although it is not clear how far the research went.

According to the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute HHI in Berlin, Germany;

“It is best suited as an additional option for data transfer where radio transmission networks are not desired or not possible – without needing new cables or equipment in the house. Combinations are also possible, such as optical WLAN in one direction and PowerLAN for the return channel. Films can be transferred to the PC like this and also played there, or they can be sent on to another computer.”
